Australia Model Code of Practice: Managing Psychosocial Hazards at Work 5.1a: 5.1 Identify possible controls and rank them from most to least effective

To decide what is reasonably practicable, identify as many possible controls as possible in consultation with workers, then consider which control or combination is most effective. First aim to eliminate the risk; then order the remaining controls from most to least effective, with reliable controls that offer the highest protection first. Minimising risk can involve changing the design of work including job demands and tasks, the systems of work (allocating tasks to match skills, allowing enough time, support from supervisors and colleagues), the work environment and conditions, workplace interactions including respectful behaviours and relationships, and the objects or tools used. Physical risks that contribute to psychosocial risk can be minimised by substitution, isolation and engineering controls. Administrative controls and personal protective equipment are the least reliable and should be considered last and combined with more effective controls, because policies can be ignored and systems misunderstood.
